If you have trouble committing to an option, it's usually because the options are equally good as far as you know.
There are two ways to go about this:
1. If the stakes are low, you can just pick one option at random and commit to it.
2. If the stakes are high, come up with a way to reduce your uncertainty around the options. Set a time limit, and perform an experiment that will inform your decision. If that experiment doesn't conclusively settle the options, just pick one and commit to it.
